Description

Technical Field

[0001] This invention relates to the field of metal product grinding and manufacturing technology, specifically to a badge edge grinding device and its process based on multi-axis linkage. Background Technology

[0002] Edge polishing of metal badges is a crucial finishing process in badge manufacturing, directly affecting not only the product's aesthetics but also its feel, security, and lifespan. Fine polishing eliminates burrs, sharp edges, and imperfections from cutting, resulting in smooth, even edges and enhancing the overall quality. After fine polishing, the badge undergoes further polishing to eliminate microscopic unevenness and achieve a mirror-like smooth edge. Finally, a thorough cleaning removes metal debris, preparing the badge for subsequent electroplating or coloring. High-quality edge polishing not only makes the badge comfortable to wear and prevents scratches but also enhances its visual appeal through rounded, smooth contours. Chinese Patent Application No.: 202010873186.7 A metal polishing device, which polishes the wrinkles on the inner and outer sides of a metal tube caused by the tangential compressive stress that shortens the inner side of the tube after bending, thereby thickening the inner wall and improving the surface accuracy and flatness of the tube wall at the bend.

[0007] Preferably, two limiting slide rails are provided, and the two limiting slide rails are symmetrically welded to the outside of the sliding column. A slide rail groove is opened on the inner side of the electric sliding seat at the position corresponding to the limiting slide rail.

[0009] Preferably, the driving gear meshes with the driven gear, and the input ends of the electric sliding seat, the rotary motor, the distance-adjusting electric push rod, and the grinding motor are all electrically connected to the output end of the internal controller.

[0010] Preferably, a fixing component is installed at the top center of the base; The fixing component includes a limiting seat; A limiting seat is installed at the top center of the base. A limiting screw is threaded to the outer arm of the limiting seat. A sliding sleeve is slidably connected to the outer side of the limiting seat. A conical platform is installed at the top of the limiting seat. A limiting electromagnet is installed at the top of the conical platform. A limiting cylinder is attracted to one end face of the limiting electromagnet. A positioning plate is slidably attached to the bottom inner side of the limiting cylinder.

[0013] According to the above technical solution, a badge edge grinding process based on multi-axis linkage includes the following steps: S1. First, place the new badge that needs to be polished at the top of the positioning ring, so that the badge is limited by the space between the limiting cylinder and the positioning ring. S2. Subsequently, the electric sliding seat slides down, driving the stabilizing arm to move towards the badge position. The distance adjustment electric push rod at the top of the fixed sleeve retracts, and the multi-faceted polishing roller moves to the top position of the badge. S3. Next, turn on the rotating motor. At this time, the rotating motor will drive the drive gear to rotate. By adjusting the rotation of the sleeve, the stabilizing arm can be rotated at the same time. S4.

[0014] Compared with the prior art, the beneficial effects of the present invention are: the present invention has a scientific and reasonable structure and is safe and convenient to use. 1. Equipped with a grinding device, the multi-faceted grinding roller can move along multiple axes by adjusting the rotation of the sleeve, the lifting and lowering of the electric sliding seat, and the extension and retraction of the grinding motor. This allows the multi-faceted grinding roller to reach any position on the top surface of the metal badge, uniformly grinding burrs and protrusions on the badge surface. It can grind not only regular badges of different sizes, but also high-quality badges of various irregular shapes, further improving the quality of the badges. Furthermore, because the badge is clamped and suspended by the clamping rod and clamping seat, the multi-faceted grinding roller can be moved to the bottom of the badge for rapid grinding without having to flip the badge over, further improving work efficiency and ensuring badge quality.

[0015] 2. Equipped with a fixing component, when processing badges of different shapes and sizes, simply attach the top of the limiting cylinder to the corresponding mold. This ensures that when the sliding clamping rod rises from the bottom, it can always lift the device from the same position on the badge of the same size. This ensures that when grinding the badge edges, the edited program can produce badges of the highest quality. After a stage of work is completed, loosen the limit screw and slide the sliding sleeve downwards. When the top of the sliding sleeve is lower than the top of the limit seat, a large amount of waste will fall to the ground, which can quickly collect the waste, further improve work efficiency, prevent the flying waste from injuring the operator, and ensure the safety of the operation.

[0023] A fixing component 3 is installed at the top center of the base 1; The fixing component 3 includes a limiting seat 301, a limiting screw 302, a sliding sleeve 303, a conical platform 304, a limiting electromagnet 305, a limiting cylinder 306, a positioning plate 307, a sliding clamping rod 308, a clamping seat 309, a positioning ring 310, a clamping cylinder 311, and a sliding through groove 312.

[0024] like Figure 8 As shown, according to the above technical solution, a badge edge grinding process based on multi-axis linkage includes the following steps; S1. First, place the new badge that needs to be polished at the top of the positioning ring 310, so that the badge is limited by the space between the limiting cylinder 306 and the positioning ring 310. S2. Subsequently, the electric sliding seat 204 slides down, driving the stabilizing arm 212 to move towards the badge position. The distance adjustment electric push rod 216 at the top of the fixed sleeve 214 retracts, and the multi-faceted polishing roller 219 moves to the top position of the badge. S3. Next, turn on the rotating motor 206. At this time, the rotating motor 206 will drive the drive gear 207 to rotate. By adjusting the rotation of the sleeve 209, the stabilizing arm 212 can be driven to rotate at the same time. S4. Then, turn on the polishing motor 218 and adjust the rotation of the sleeve 209, the lifting and lowering of the electric sliding seat 204, and the extension and retraction of the polishing motor 218 so that the multi-faceted polishing roller 219 can polish any part of the metal badge. S5. Finally, during the polishing process, a large amount of waste will splash onto the inner wall of the sliding sleeve 303. Loosen the limiting screw 302. When the top of the sliding sleeve 303 is lower than the top of the limiting seat 301, a large amount of waste will fall to the ground. Clean up the waste.

[0025] The working principle and usage process of this invention are as follows: First, when the operator is polishing the badge, the badge is clamped and fixed by the clamping rod 220 and the clamping seat 309. At this time, the electric sliding seat 204 is controlled to slide downward, thereby driving the stabilizing support arm 212 to move towards the badge position. When the stabilizing support arm 212 moves to the appropriate position, the distance adjustment electric push rod 216 at the top of the fixing sleeve 214 is controlled to retract, thereby driving the polishing motor 218 to move towards the badge position. When the multi-faceted polishing roller 219 is at the top surface of the badge, the initial position adjustment is completed. Next, the operator turns on the rotating motor 206. At this time, the rotating motor 206 will drive the driving gear 207 to rotate. Since the adjusting sleeve 209 meshes with the driving gear 207 through the driven gear 211, the adjusting sleeve 209 will rotate on the outside of the bearing 210 under the drive of the driving gear 207. By adjusting the rotation of the sleeve 209, the stabilizing arm 212 can be rotated simultaneously. Then, the grinding motor 218 can be turned on, which will drive the multi-faceted grinding roller 219 to rotate at a constant speed, thereby grinding the surface of the metal badge. While rotating, by adjusting the rotation of the sleeve 209, the lifting and lowering of the electric sliding seat 204, and the extension and retraction of the grinding motor 218, the multi-faceted grinding roller 219 can be moved in multiple axes, allowing it to reach any position on the top surface of the metal badge and grind the burrs and protrusions on the badge surface at a constant speed. It can not only grind regular badges of different sizes, but also high-quality badges of various irregular shapes, further improving the quality of the badge. Furthermore, since the badge is clamped and suspended by the clamping rod 220 and the clamping seat 309, the multi-faceted grinding roller 219 can be moved to the bottom of the badge for quick grinding without having to flip the badge over, further improving work efficiency and ensuring badge quality. Finally, after grinding a badge, the clamping cylinder 311 can be controlled to retract, thereby moving the sliding clamping rod 308 downward. At this time, the badge can be removed. Then, the sliding clamping rod 308 is retracted again. After the clamping seat 309 is lower than the positioning ring 310, the new badge to be ground is placed at the top position of the positioning ring 310. The badge is then limited by the space between the limiting cylinder 306 and the positioning ring 310. When processing badges of different shapes and sizes, the top of the limiting cylinder 306 only needs to be engaged with the corresponding mold. This ensures that when the sliding clamping rod 308 rises from the bottom, it can always lift the badge from the same position of the same size. This ensures that when grinding the badge edges, the edited program can produce badges of the best quality. Furthermore, during the grinding process, a large amount of waste debris will splash onto the inner wall of the sliding sleeve 303. At this time, it will slide down along the sliding sleeve 303 and collect at the bottom of the conical platform 304. After a stage of work is completed, the limiting screw 302 is loosened and the sliding sleeve 303 is slid down. When the top of the sliding sleeve 303 is lower than the top of the limiting seat 301, a large amount of waste debris will fall to the ground, which can quickly collect the waste debris, further improve work efficiency, prevent the splashed waste debris from causing injury to the operator, and ensure the safety of the operation.

[0026] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
